The present invention relates to a lighting system for flat full-fashioned knitting machines.

In machines of this general description now in use, it has been found iflicult with the usual overhead lighting to pr ide an adequate illumination of the knittinginstrumen'talities and their associated loop forming elements which will cause these elements to stand out sharply from one another to assist the operator in the performance of various manual operations such as the setting up and turning ofthe welt with the usual welt rake, and in the finding and correcting of faults in the alignment and operation of these elements. Where in accordance with the usual practice, it relatively powerful lights are provided above the entire machine, the shadows cast by intervening mechanisms and the reflected light from other machine parts, tend to blur these elements, so that the operator has difficulty in distinguishing one from the other. t

It is a principal object of the present invention to provide a novel and improved lighting system which will enable light to be'directed onto the needle series and their cooperating knitting elements in such a manner as-to throw these parts into sharp relief, so that the operator maywithout dimculty see these'elements'in their minutest detailaand is enabled by virtue of the relation of light and shade thereon, to detect the slightest variations in alignment or register of the many cooperating elements.

With these and other objects in view as may hereinafter appear, a principal-feature of themvention consists in the provision of sources of light located directly above and in close proximity to the needles, and arranged to direct the light downwardly in such a manner as to provide a substantially even illumination the length of the needles series, and to produce a relationship of light and shadow on and between the individual elements to render these separately and individually distinguishable to the eye of the operator.

The several features of the invention consist also in the devices, combinations and arrangement of parts hereinafter described and claimed, which together with the advantages to be obtained thereby, will be readily understood by one skilled in the art from the following description taken in connection with the accompanying drawin in which the single figure is, a view in front elevation of a portion of a flat full-fashioned knitting machine of ordinary description, only so much of the machine being shown as is believed necessary to illustrate the connection of the present invention therewith.

In the drawing which discloses one full section of a multiple section full fashioned machine, and portions of the adjacent sections on each side thereof, the needle bars are showngeneral 1y at l. The location of the usual knitting instrumentalities on the machine including sinkers, knockers and needles movable with relation to the usual press edge, follows the usual arrangement in these machines, and while not shown, will be readily understood by one skilled in the m art from the position of. the needle bars 1 and the I sinker supporting rail ll illustrated in the drawing. The machine is further provided with the usual narrowing machine frame including the vertically movable shaft 2 having supported 16 thereon the usual narrowing pointbars 3 and l slidably mounted in depending brackets 5 and 6 secured to the narrowing machine shaft 2. As illustrated in the drawing, one of these brackets 5 or 6 is located between each two adjacent 2o knitting sections of the machine.

in carrying out the present invention, a light bracket I is secured to each of the brackets 5 or 6 having mounted thereon two low power lamps 8 and reflectors 9 which serve to direct light beams in a substantially vertical plane downwardly onto and along each needle series as indicated in dotted lines in the drawing. The arrangement of the two lights 8 and reflectors 9 associated with each section, is such' as to cast anarrow beam of light onto the needles which is not interrupted by any intervening parts of the I machine, and avoids any interference with the desired relation of light and shadow on the needles which might be caused by the reflection of light from other machine parts.

In addition to the advantages of direct and unobstructed illumination of the needles and associated parts obtained by mounting light sources on the narrowing frame directly overthe needies as above described, a further advantage is secured which consists in the creation of a sharply defined pattern of light and shadow by means of which each individual element is thrown into sharp relief. Any imperfections or misalignment of the needles or their cooperating knitting elements will operate to distort the otherwise regular pattern of light and shadow, and will thus through easily visible means, attract the attention of and'assist the operator in eliminating the trouble.

It will be understood that the invention is not limited to the specific embodiment shown, and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.

What is claimed is:

1. In a flat full-fashioned knitting machine having knitting devices including a needle series, and certain machine parts including a narrowing frame located substantially over the needles, an electric lighting system which comprises supporting means on the machine, a light source supported thereon above the needles in close proximity thereto and substantially in a vertical plane passing through the needleseries to provide a direct evenly distributed illumination of the needle series unobstructed by said certain parts.

2. In a flat full-fashioned knitting machine having knitting devices including a needle series. and certain machine parts including a narrowing frame located substantially over the needles, an electric lighting system which comprises supporting means on the machine, a light source supported thereon above the needles in close proximity thereto and substantially in a vertical plane passing through the needle series to provide a direct illumination of the needle series, and means for directing the light from said source to secure a sharply defined relation of light and shadow between'the individual needles unobstructed by saidcertain parts.

3. In a 11st full-fashioned knitting machine having knitting devices including a needle series.

and .a narrowing frame, an electric lighting system which comprises light sources of small intensity located on the narrowing frame between knitting sections in close proximity to and substantially in a vertical plane passing through the needle series, and means associated with each of said light sources 1hr directingthe light onto the needle series to secure a sharply defined relation of light and shadow between the individual needles.

4. In a flat full-fashioned knitting machine having knitting devices including a needle series and a narrowing frame, a lighting system which comprises small electric lamps of low light intensitylocated on the narrowing frame at each .end of a knitting section above the needles-and in close proximity thereto substantially in a vertical plane passing through the needle series to provide a direct illumination of the needles, and

' a reflector associated with each of said lamps from said sources onto the needles to secure a sharply defined relation of light and shadow between the individual needles.

6. In a flat full-fashioned multiple section knitting machine having knitting devices including a needle series for each section, and certain machine parts including a narrowing frame 10- catedsubstantially above the needles, a lighting system which comprises supporting means on the machine, light sources associated with each section supported thereon above the needles in close proximity thereto'and substantially in a vertical plane passing through the needle series to provide a direct illumination of the needle series unobstructed by said certain machine parts.
